> Consider the case where application A and B are running under the same domain example.com.
A is served by an Apache Felix (below https://example.com/A) and only supports HTTPS (being
terminated e.g. by a LoadBalancer in front). B is served by some other application server
(below https://example.com/B) and only supports HTTP.
> Now I create a link from A towards B with {{HttpServletResponse.sendRedirect("http://example.com/B/somepath")}}.
> This URL is automatically converted by the SslFilter to {{https://example.com/B/somepath}}
which is clearly not intended.
> I think the sendRedirect(...) implementation of the SSLFilter from FELIX-4420 is way
too aggressive, because it will also rewrite absolute URIs already containing a scheme.
> Actually absolute URIs should never been rewritten by that filter, only relative ones
(starting with a "/").
